Variety Description
Varieties used for comparison: 'Eckanezka' (Prestige Early Red) and '490' (Freedom Red)
Summary: Development of the lobes of the leaf blade is absent to very weak for 'PER2084' while it is weak to moderate for for both reference varieties. The margin of the leaf blade of 'PER2804' has weakly scalloped incisions whereas that of the reference varieties have no incisions. 'PER2084' has more transition bracts than 'Eckanezka'. Rugosity between the veins of the bracts is absent for 'PER2084' while it is absent to weak for both reference varieties. 'PER2804' has narrower bracts than '490'. The base of the largest bract is wedge shaped for 'PER2084' while it is round to truncate shaped for '490'. 'PER2804' has a broader cyathium and larger cyathium glands than both reference varieties.

Origin & Breeding History: 'PER2804' was discovered in December 2003 at the Paul Ecke Ranch in Encinitas, California, U.S.A. 'PER2804' was selected based on its vigorous growth habit, bright red bracts and earliness of flowering.
Tests & Trials: Trials for 'PER2804' were conducted during the fall of 2007 at Schenk Farms & Greenhouse Co. Ltd. in St. Catherines, Ontario. There were 25 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings transplanted into 15 cm pots on August 16, 2007. The pots were spaced 30 cm apart, pot centre to centre. Measured characteristics were based on measurements taken from 10 plants or parts of plants on December 3, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
